摘要
研究多孔介质中可压缩可混溶两相渗流驱动问题的计算方法:压力方程用有限元方法求解,饱合度方程用特征线修正有限差分方法求解,构造了全离散数值计算格式。
A numerical method is studied for compressible miscible displacement in porous media.The pressure equation is discretized with finite element method,while the saturation equation is solved by finite difference method combining with the modified method of characteristics.Optimal error estimate in H 1 norm is proved.
